WOGDWORKING MACHINE.

My invention relates to woodiworkingmachines particularly adapted foruse in alteringrwindow sashes and doors to permit the application ofweather strips thereto. Herewhich consists in surfacing, heveling,grooving; and rabheting portionswof the windowsash, has beenperformedbyaskilled workmen with the useof hand tools. l hewprincipalobjection to this method of alteri-ngthe window sashes is that itrequires considerable time ,and is quite expensive.

One 1 of rthe principal objects of the .present ilmentionisxto produceasmall andcompact power driven woodworking machine, whichcan beHcasil-ytransported from place to place: and which will easily and cheaplypenform upon the StLSllBSqOl? door (the plurah ity of operationsrequiredfor the installation of weather strips. Other objects are simplicity andcheapness iii-construction.

The: invention consists principally in (the improved woodworkingmachine; hereinafter shown and described; and it also: consists in the.combinations and arrangements of parts hereinafter describedandclai'med,

the accompanying drawings, which form part of this specification and.wherein like symbols refer to like ,parts wherever they occur, a i

Referring :to the accompanying drawings, my woodworkingmachine comprises a box likeihousing or frame .10 which is supported atits four cornersby leg members L1. The box-like housing 10. is. providedat its top with ani'orwardly cxtendz1ng.. table portion. 12

adapted 1i10= support the work. The work supporting table has a narrowopening 13 extending vertically therethrough from end.

to end thereof, and ,it is: also provided immediately above the box-likesupporting body with openings that are closed. by cover plates 14;.Located beneath the .cover plates- 14 is a horizontal shaft 15, whoseends are. journal'ed insuitable. bearings 16 atopposite sides of thehousinglO.

The cutter shaft has. different forms of cutter heads secured: theretonamely, a rabhetin-g head 17;, a grooving head 18, a narrow jointinghead 1.9,,and .a wide jointing head- 20. The cutter shaft 15 extendsthroughopenings provided therefor in the side walls iof the housing l0and is provided atone end :Wltlllil. cutter head 21 andat its other endwith. a cutter head 22. The chief difi'erence between the cutter. heads'17,, 1.8, 119,, and 20= and the endzicutter heads 21 and: 22 is that inthe former'the bits or blades are carried upon the peripheral surfaceofthe head and are adapted "to engage the under surfaceod .the work,whereas in the latter the bits or blades are carried upon the endsurfacezof the head and are adapted .to engage LthB side of the work.The fend cutters 21 and .22 have side and end cuttinged-ges; and thecutiis made first pressing the side of the work against the cutter,whichgbores its way out of the side of. the work, after which. the workis. moved transversely of the cutter, which, by cutting on. its side,extendsv the cut @to any desired length. The cutter heads 17, 18,, 19,and- .20 work inv openings ,provided therefor in the cover plateslO andare arranged so that the cutting edges pass above the plane. ofithe worksupporting table so astoengage the under surface of the work. as itisinoved with reference tosaid cutters. nection,.-iti is noted that thecover .plates are removablysecured imposition meansof in ithei'drawing,the. electric motor is sup" In this conported on a bracket, 27 securedto the. housing 10. The. sprocket chain is, ,ronided, witha suitableguardorcasing 28 ibr preventing injury to the workmenlhy contact withsaid chain, The cutter heads 17, 18, 19, and 20 are provided with guards29 which serve to prevent injury to the workmen by contact with thecutting edges of said cutter heads. Each of these guards comprises asemi-circular plate having a hub portion sleeved on the cutter shait andan arcuate outer flange or hood portion adapted to overlap the upperportion of the cutter head.

The forward end portion of the areuatc flange of each cutter head isprovided with a curled portion adapted to abut against the forward endof the cutter openings in the cover plates. The cutter guards arenormally yieldably held with their hood portions covering the upperportions of the cutters by means of coil springs 30, one end of a springbeing secured to the rear wallet the hollow housing and the other endbeing secured to the lower portion of a cutter guard. The curled upperend portions of the cutter guards 29 project above the work supportingtable and are adapted to be swung rearwardly below the surface of thetable when engaged by the work. The end cutters 2i and 22 are alsoprovided with cutter guards 31. Each of these end cutter guardscomprises a spring-pressed cuplike member 32 which fits over the endcutter and normally projects beyond the cutting edge thereof, therebypreventing injury to the workmen by contact with the cutter. The endcutter guards are. slidably supported on pins 33 (see Fig. (3) that arethreaded into the side walls of the housing 10 and are adapted to extendinto holes provided therefor in the cutter guards. The end cuttersoverlap the outer ends of the cutters and are normally held in saidposition by means of coil springs 33- slecved on one of each pair ofsupporting pins 33, which pin is provided with a head portion whichserves to limit the outward sliding movement of the end cutter guard.The end cutter guards are provided with forwardly projecting horizontalfinger portions 31 that are curved inwardly thereby forming camsurfaces, which, when engaged by the work, cause said cutter guards tomove inwardly and thus permit the cutting edges thereof to engage theside of the work.

The work that is to be engaged by the end cutters is supported onhorizontally disposed plates 3% located below the end cutters onopposite sides of the housing 10. These plates are supported forhorizontal sliding movement in directions transverse to the axes of theend cutters in slideways 35 formed in the horizontally extending portionof bracket members 36 and 37 secured to the side walls of the housing.The bracket member 36, which supports the table slide located adjacentto the end cutter 21 at the left-hand side of the machine, is bolted orotherwise immovably secured to the side walls of the box-like housing.The bracket 37. which supports the table slide located adjacent to theend cutter 22 at the righthand side of the machine, has a slot and boltconnection 38 with the side wall of the hollow housing, the slotsextending vertically, whereby said bracket member is adapted forvertical adjustment to vary the height of the slide plate with relationto the end cutter. This vertical adjustment of the vertically adjustabletable bracket 37 is accomplished by means of a vertically disposed screw39 which is threaded through a bracket 40 secured to the side wall ofthe housing beneath the bracket 37. The upper end portion of the screw39 projects through a hole in the bracket 37 and endwise movement ofsaid screw with relation to the bracket is prevented by means of collars41 that are pinned to the screw above and below the bracket. Theadjusting screw 39 is manipulated to raise and lower the slide platecarried by the bracket 37 by means of a hand wheel 42 secured to thelower end of said adjusting screw.

The work is yieldahly held in contact with the end cutters by means ofpressure pads 43 located opposite said cutters. The pressure pads restflatwise on the outwardly extending flanges of brackets 4%, whosedepending flanges are rigidly secured to the outer faces of the tableslides. These pressure pads comprise rectangular blocks having slot andscrew connections 45 with the brackets 4.4: adapted to permit horizontalsliding movement of said blocks towards and away from the end cutters.The inner marginal portions of these pressure blocks are provided with amultiplicity of spring teeth 40 adapted to yieldably engage the outerside face of the work and hold the same in contact with the end cutters.The pressure pads are adjusted towards and away from the end cutters bymeans of adjusting screws 4:7 that are threaded through the upstandingflanges of the supporting brackets for said pressure pads.

The machine is provided adjacent to each of the cutter heads with upperand lower work guides capable of being lengthened or shortened. Each ofthese guides con'iprises two telescoping U-shaped tubular members 48 and49 whose horizontally spaced parallel branch portions are adapted toslide one within another. The upper and lower telescopic members arearranged with their respective b'anches one above the other, the outerbranches serving as guides for work engaged by the end cutter head 22and the inner branches serving as guides for work engaged by the cutterhead 20. Both branches of the outer tubes 48 of the upper and lowerguide members extend through openings provided therefor in blocks 50that are sleeved on posts 51 which are held in vertical openings at thefront and rear corners oi the table by thumb screws 52.

Projecting from the rear eornerswo f the machine .are brnekets 81udapted toslidably support "horizontal etllbQS or 1'ods 82,one end ofwhich is located in the plane oifi theilower work guides. These rods or"tubes extend rearwurdl-y and are vsupported in blocks 83 on the ends ofthe slidahle sections ofthe lower work guides. Posts "84 project up wardly from the blocks 83 and sli'dnbly support blocks 85, which, in turn,supportthe sliduble section of the upper "work guides. Theblocks 85 areadjustable up and "down on *theposts 84and are locked in the desiredposition by set screws 86. Located below and extending transversely ofthe work guides is a cross tube 87 which issripported at its oppositeends by brackets SS-slidztbly mounted on the tubes 82. A similar rod- 89is supported-in portions that depend froin theblocks 83. The rods 87and89' areprovided with upstanding brackets 90 having bifurcated outerend portions between which are j'ourna'led rollers '91. These rollers:are disposedwith their uppersurfaces on a level with the'top surfaceofthe work supporting tableand with their {LXBS disposed transverse to thedireetion in which the work travels and thus constitute roller supportsfor the work as it dezrves t'hetu ble. r

The-operation of the machine is as follows it is desired to operate"upon the side of the work, such, for instance, as the side faces of themeeting rails of the upper and lower sashes of a window, end cutters ofa shape necessary to perform the desired operation are secured to theends of the cutter shaft, and the pressure blocks 43 are then adjustedto hold the work against the work guides. Thesashes may then be placedonthe slide plates 34- in an upright position and moved transversely ofthe end cutters which engage the side of the sash and make the desiredcut. lVhen it is desired to rabbet, groove, or surface an edge of thesash, the sash is placed on the table in line with the desired cutterhead and, the spring rollers adjusted to hold it against the work guidestherefor. The work is then slid along the table into engagement with thecutter head which performs the desired o ieration.

It is obvious from the foregoing description that my woodworking machinevery simple in construction; that it can be readily transported fromplace to place: that it is adapted to quickly and accurately performupon the sashes, either simultaneously or independently, the operationsdesired; and that it can be quickly adjusted to accomodate work ofdifferent shapes and sizes.

Obviously the hereinbefore described machine admits of considerablemodification without departing from the invention; therefore, I do notwish to be limited to the exact details of construction shown anddescribed.
